  • U.S. Offshore Wind Market Report & Insights 2020
    RAMPION OFFSHORE WIND FARM — COURTESY OF ATKINS THE BUSINESS NETWORK FOR OFFSHORE WIND U.S. OFFSHORE WIND MARKET REPORT & INSIGHTS 2020 MEMBERS ONLY The Business Network for Offshore Wind’s2020 U.S. Offshore Wind Market and Insights offers an analysis of federal and state government activity to better understand how it may affect your business planning and the industry holistically. The federal government has turned its attention to the burgeoning industry to offer more regulation. Congress and federal agencies beyond the Department of Interior’s Bureau of Ocean and Energy Management and U.S. Department of Energy are now affecting how the offshore wind industry will operate into the future. This report also discusses how some of the challenges facing offshore wind are being addressed. The health and safety of workers – whether onshore or offshore – are a paramount tenet within the industry. Particular- ly at this time, the offshore industry remains proactive in its response to the coronavirus epidemic, having put in place telework directives, eliminating unnecessary travel, and following government guidelines. As a result of these protocols, Europe has reported minimal disruptions to the supply chains and the 15 offshore wind projects in the U.S., remain in the planning and development stages. It is too soon to know exactly how the global COVID-19 epidemic disruption will affect the U.S. offshore wind in- dustry. Our main concern centers around the economic hardship a long-term shutdown and recession would place on secondary and tertiary U.S. suppliers. It is important to point out, however, that there is almost 10GWs of U.S.

  • Analyzing the US Wind Power Industry
    +44 20 8123 2220 [email protected] Analyzing the US Wind Power Industry https://marketpublishers.com/r/A2BBD5C7FFBEN.html Date: June 2011 Pages: 230 Price: US$ 300.00 (Single User License) ID: A2BBD5C7FFBEN Abstracts The rise of wind energy is no longer being looked upon as an alternate source of energy. The United States is a leader in the field of wind energy and the US in 2010 was the second largest user of wind energy in the world, just behind China. In fact, the US had over 40,000 megawatts of installed capacity of wind power by the end of 2010. Aruvian’s R’search presents an analysis of the US Wind Power Industry in its research report Analyzing the US Wind Power Industry. In this research offering, we carry out an in-depth analysis of the wind power market in the United States. We begin with an analysis of the market profile, market statistics, wind power generation by state, installed capacity growth, analysis of wind resources in the US, and many other points that are important for investors looking to invest in the US wind power sector. This report also undertakes a cost analysis of wind power in the US, along with an analysis of the major market trends and challenges facing the industry. The small wind turbines market in the US is analyzed comprehensively in this report as well and includes a market profile, market statistics, the emergence and importance of hybrid small wind turbines, very small wind turbines, wind-diesel hybrid turbine systems, and the economics of small wind turbines.

  • Analysis of Western Kansas Wind Power Characteristics During 2003 Kansas City Heat Waves
    July 15, 2006 ANALYSIS OF WESTERN KANSAS WIND POWER CHARACTERISTICS DURING 2003 KANSAS CITY HEAT WAVES By Craig Volland, QEP The Issue Electric Utility companies serving Kansas communities have been reluctant to commit to the purchase or installation of a significant amount of wind power in the state. Though KCP&L is investing in one 100.5 MW wind farm near Spearville, they are also proceeding to build a 850 MW coal- fired power plant by 2010 near Weston, Mo., Westar has announced plans for a large coal plant by 2013. Sunflower Electric, with partners, has announced plans for three 650 MW coal-fired boilers near Holcomb, Kansas, and the Bureau of Public Utilities of Kansas City, Kansas has announced plans to build a 250 MW or larger coal plant by 2012 next to their Nearman power station. Both KCP&L and Westar have indicated that wind power is too unreliable for their needs. That is, wind generation may not be sufficient when they need power the most such as during summer heat waves in their service areas. For example, Westar indicated this concern in their slide presentation to the Senate Utilities Committee in the Kansas legislative committee on February 1, 20051. They showed a slide comparing the power generated by the Blue Canyon Wind Farm in Oklahoma during August 2, 2004 compared to their load that day. In proceedings of the Kansas Corporation Commission KCP&L has noted that only 5 to 10 % of wind power output will be accredited by the WPP, the regional transmission authority, as “dispatchable” for meeting peak demand.2 The wind industry responds that temporary declines in wind generation can be reasonably well predicted in advance and compensated for by other sources on the grid, such as gas-fired “spinning reserve” or by purchased power.

WOODY 2020 All Rights Reserved. ABSTRACT ‘WHEN THE WIND COMES RIGHT BEHIND THE’ … SALES PITCH: ALTERNATIVE VIEWS TO WIND ENERGY DEVELOPMENT IN A RURAL OKLAHOMA HOST COMMUNITY By Tanya S. Woody Wind energy development has expanded across the prairie of northwest Oklahoma over the past 17 years. Several factors contributed to the success of wind energy in the state including a volatile economy history spurring a need to diversify the energy-based economy, ideal wind power potential, and state and host community support fueled by a rural benefit narrative. Starting in the early 2000s, the state and rural oil and gas communities familiar with the hardships of volatile fuel markets embraced wind projects as a means to strengthen their local economies and ameliorate rural disadvantages. Literature on the impacts and perceptions of wind energy benefits for host communities, however, remains divided, and little is known about realistic effects and perceptions in the context of a pre-existing energy culture and economy.

  • Evolutionary Multi-Objective Energy Production Optimization: an Empirical Comparison
    Mathematical and Computational Applications Article Evolutionary Multi-Objective Energy Production Optimization: An Empirical Comparison Gustavo-Adolfo Vargas-Hákim 1,*, Efrén Mezura-Montes 1 and Edgar Galván 2 1 Artificial Intelligence Research Center, University of Veracruz, Sebastián Camacho 5, Col. Centro, Xalapa 91000, Veracruz, Mexico; [email protected] 2 Naturally Inspired Computation Research Group, Department of Computer Science, Maynooth University, Maynooth W23 F2K8, Kildare, Ireland; [email protected] * Correspondence: [email protected] Received: 21 April 2020; Accepted: 15 June 2020; Published: 16 June 2020 Abstract: This work presents the assessment of the well-known Non-Dominated Sorting Genetic Algorithm II (NSGA-II) and one of its variants to optimize a proposed electric power production system. Such variant implements a chaotic model to generate the initial population, aiming to get a better distributed Pareto front. The considered power system is composed of solar, wind and natural gas power sources, being the first two renewable energies. Three conflicting objectives are considered in the problem: (1) power production, (2) production costs and (3) CO2 emissions. The Multi-Objective Evolutionary Algorithm based on Decomposition (MOEA/D) is also adopted in the comparison so as to enrich the empirical evidence by contrasting the NSGA-II versions against a non-Pareto-based approach. Spacing and Hypervolume are the chosen metrics to compare the performance of the algorithms under study. The obtained results suggest that there is no significant improvement by using the variant of the NSGA-II over the original version. Nonetheless, meaningful performance differences have been found between MOEA/D and the other two algorithms.

Ocean-based renewables represent 10% of the global emissions Offshore wind and other marine renewables reductions needed by 2050 to stay under a 1.5°C warming represent 45% of emissions reduction potential in scenario. It represents the largest opportunity to reduce carbon the ocean according to the High-Level Panel emissions through marine activities. Of the existing technologies that generate electricity from the ocean, offshore wind is the most commercially advanced. The sector has grown ~30% per year since 2010 and contributed 1% to global electricity generation in 2019, but its future is far from certain. Project development can take a decade, costs billions of dollars, and can be derailed by multiple stakeholders including fishers, local communities, shifting political regimes, regulatory uncertainty, and conservation concerns. To date, there has been surprisingly little investment by the philanthropic community despite the need. We believe that philanthropy can have an outsized impact in this key climate-wedge through targeted grantmaking.
